Blizzard's follow-up to World of Warcraft, a project known only by its codename Titan, has been in development since 2006. And it's going to be in development a lot longer, after the company announced today it was making some significant changes to both the game and the people working on it.

The people who make MMO juggernaut World of Warcraft have another massively multiplayer online game in the works, a game they're calling Titan for now. Blizzard calls it "awesome" and "ambitious." One analyst calls it "casual."
